Abstract (en)
[origin: US2002045729A1] A method for lateral chain modification of aryl main chain polymers with aromatic ketones or aldehydes containing tertiary basic N-groups is described. The modification can be accomplished via addition of an aromatic carboxylic acid or an acid derivative containing a tertiary amine moiety to a metallized polymer. The tertiary amines on the modified polymer can be converted to quaternary amines with halogen alkanes. Modification of the aryl main chain polymers with aromatic groups containing sulphonic acid radicals is also described. The polymers formed can be crosslinked and prepared for use in a wide variety of membrane technologies including ion exchange, dialysis, reverse osmosis, nanofiltration.
